The community prevalence of depression in older Australians

Testosterone and aging male, a perspective from a developing country

PURPOSE

Hypogonadism is associated with a wide range of physical and psychological symptoms that can affect the overall health of men. However, in a developing country, there are several imposing challenges in the diagnosis and treatment of hypogonadism, including a lack of awareness and understanding of the condition among healthcare providers and patients, limited resources and the high cost of treatment. This review aimed to examine the potential benefits and risks of testosterone replacement therapy (TRT) and provides a perspective of a developing country on the topic.

MATERIALS AND METHODS

A comprehensive literature review was conducted to gather relevant information on the impact of testosterone deficiency on ageing males and the effectiveness of TRT for treating hypogonadism. Published peer-reviewed articles were analyzed to evaluate the benefits and risks of TRT. Additionally, the unique challenges faced in the diagnosis and treatment of hypogonadism in a developing country were considered.

RESULTS

Testosterone replacement therapy has been shown to be an effective treatment for hypogonadism, particularly in symptomatic men with low testosterone levels. It offers potential benefits such as improvements in symptoms and overall quality of life. However, there are associated risks and side effects that need to be considered. In a developing country, challenges such as limited awareness and understanding of hypogonadism, resource constraints, and high treatment costs pose additional barriers to accessing TRT and comprehensive care.

CONCLUSION

In conclusion, TRT holds promise as a treatment for hypogonadism, but its implementation and accessibility face significant challenges in a developing country. Addressing these challenges, including raising awareness, allocating resources, and finding cost-effective solutions, is crucial for ensuring that men with hypogonadism in such settings receive appropriate diagnosis and treatment. Further research and efforts are needed to improve the management of hypogonadism in developing countries and optimize the potential benefits of TRT for affected individuals.

Community pharmacists' acceptability of pharmacist-delivered depression screening for older adults: a qualitative study

BACKGROUND

Late-life depression often goes underdiagnosed and undertreated, affecting the quality of life of older adults. Pharmacists are well-placed to identify older adults who may be at risk of depression by using appropriate screening tools.

AIM

To explore community pharmacists' acceptability of performing late-life depression screening in Australian community pharmacies.

METHOD

Semi-structured interviews with community pharmacists were conducted to gauge their perceptions regarding delivering depression screening services for older adults. Data analysis was conducted using an iterative, inductive approach. Key themes were identified, which were further explored and divided into subthemes. Subthemes were categorised as either barriers or facilitators. Each subtheme was mapped to the Capability, Opportunity, Motivation-Behaviour model by classifying whether they impacted pharmacists' capability, opportunity, or motivation regarding depression screening.

RESULTS

Fifteen pharmacists were interviewed, 12 of whom were female and 11 of whom practised in a metropolitan area. Four key themes were identified including: training needs, environmental factors, pharmacists' roles, and organisational support, which were further divided into 13 subthemes. Three subthemes were mapped to Capability, seven to Opportunity and three to Motivation. Barriers included lack of resources and lack of remuneration, while facilitators included training, pharmacists' accessibility, and rapport with consumers.

CONCLUSION

The findings of this study demonstrate that while community pharmacists found depression screening for older adults in community pharmacies to be an acceptable service, there remains a need for the development of funding schemes and standardised guidelines for pharmacist-delivered depression screening for older adults.

Quality of life and psychological health after mild traumatic brain injury in older people: Three- and six-month follow up

OBJECTIVES

Examine quality of life (QoL) and psychological health after mild traumatic brain injury (mTBI) in older people (65+ years) at 3- and 6-month follow-up and explore which injury factors predicted QoL.

METHODS

mTBI patients were compared to trauma comparison (TC) and community comparison (CC) groups. QoL and psychological health were measured at both timepoints. After accounting for 3-month psychological health, injury severity, neuroimaging, and 3-month neuropsychological performance were assessed as predictors of 6-month QoL.

RESULTS

Overall 3-month QoL was lower for mTBI (Cohen's d = 0.938) and TC (Cohen's d = 0.485) groups compared to CCs, but by 6 months only mTBI patients continued to report poorer overall QoL (Cohen's d = 0.577) and physical QoL (Cohen's d = 0.656). Despite group differences, QoL for most (~92%) was within normative limits. 3-month psychological health predicted QoL 6-months postinjury (β = -.377, 95% CI -.614, -.140) but other proposed risk factors (GCS <15, neuroimaging, 3-month neuropsychological performance) did not uniquely predict QoL.

CONCLUSIONS

Older adults following mTBI reported lower QoL up to 6-months postinjury compared to non-injured peers, indicating that mTBI patients were particularly susceptible to ongoing differences in QoL 6-months postinjury.

Study protocol for ELders AT Ease (ELATE): a cluster randomised controlled trial of cognitive behaviour therapy to reduce depressive symptoms in aged care residents

BACKGROUND

This protocol describes a study of the effectiveness of cognitive behaviour therapy (CBT) for reducing depressive symptoms in older adults living in residential aged care (RAC) facilities in Australia. Depressive symptoms are highly prevalent in this population, yet the benefits of CBT for reducing such symptoms in RAC facilities have not been widely investigated. Elders at Ease (ELATE) is a 16-session CBT intervention designed for implementation in RAC facilities. The intervention includes cognitive, behavioural and reminiscence strategies and is delivered by mental health trainees (MHTs) in collaboration with RAC facility staff and residents' family.

METHODS AND ANALYSIS

ELATE will be evaluated using a cluster randomised trial comparing outcomes for residents who participate in the intervention with those living in usual care control facilities. The participants are RAC residents aged 65 years or above, with depressive symptoms (Patient Health Questionnaire-2 ≥ 3) and normal cognition or mild cognitive impairment (Standardised Mini Mental Status Examination ≥ 21). They are assessed at four time points: baseline prior to randomisation (T1), mid-treatment (T2; 2.5 months post randomisation), post-treatment (T3; 5 months post-randomisation) and 3-month follow-up (T4; 8 months post randomisation). The primary outcome is change in depressive symptoms between T1 and T3. Secondary outcomes are depressive symptoms at T4, anxiety, suicide ideation, sleep problems, quality of life, staff and family knowledge of late-life depression, stress levels and efficacy in caring for residents, and MHT levels of geropsychology competencies. Residents receiving the intervention are hypothesised to report a greater decrease in depressive symptoms between T1 and T3 compared to residents receiving usual care. The primary analysis is a regression, clustered over site to account for correlated readings, and independent variables are condition and depressive symptoms at T1. A cost-utility analysis is also undertaken.

DISCUSSION

ELATE is a comprehensive CBT intervention for reducing depressive symptoms in RAC residents. It is designed to be implemented in collaboration with facility staff and residents' families, individually tailored to residents with normal cognition to mild cognitive impairment and delivered by trainee therapists. ELATE offers a model that may be widely applicable across the RAC sector.

Ninjinyoeito Prevents Onset of Depression-Like Behavior and Reduces Hippocampal iNOS Expression in Senescence-Accelerated Mouse Prone 8 Mice

Late-life depression is a globally prevalent disorder. Ninjinyoeito (NYT), a traditional Japanese herbal medicine, attenuates depressive symptoms in older patients. However, the mechanisms underlying the antidepressive effect of NYT are unknown. In this study, we investigated the mechanism of the action of NYT using senescence-accelerated mouse prone 8 (SAMP8) mice, which exhibit accelerated aging. SAMP8 mice were treated with NYT starting at 12 weeks of age. Twelve-week-old SAMP8 mice did not show prolonged immobility time in the tail suspension test compared with age-matched SAMR1 mice (normal aging control). At 34 weeks of age, vehicle-treated SAMP8 mice displayed prolonged immobility time compared with SAMR1 mice. NYT-treated SAMP8 mice showed a shorter immobility time than that of vehicle-treated SAMP8 mice. Notably, NYT decreased hippocampal inducible nitric oxide synthase (iNOS) expression in SAMP8 mice. There was no difference in iNOS expression between SAMR1 and vehicle-treated SAMP8 mice. Subchronic (5 days) administration of an iNOS inhibitor, 1400 W, shortened the immobility time in SAMP8 mice. These results suggest that NYT prevents an increase in immobility time of SAMP8 mice by decreasing iNOS levels in the hippocampus. Therefore, the antidepressive effect of NYT in older patients might be mediated, at least in part, by the downregulation of iNOS in the brain. Our data suggest that NYT is useful to prevent the onset of depression with aging.

Prevalence and factors associated with mental health problems of psychological distress and depression among rural Victorians - analysis of cross-sectional data (Crossroads II)

BACKGROUND

Research suggests that rates of mental illness are similar in rural and urban Australia, although there are significant workforce shortages in rural regions along with higher rates of chronic disease and obesity and lower levels of socioeconomic status. However, there are variations across rural Australia and limited local data on mental health prevalence, risk, service use and protective factors. This study describes the prevalence of self-reported mental health problems of psychological distress and depression, in a rural region in Australia and aims to identify the factors associated with these problems.

METHODS

The Crossroads II study was a large-scale cross-sectional study undertaken in the Goulburn Valley region of Victoria, Australia in 2016-18. Data were collected from randomly selected households across four rural and regional towns and then screening clinics from individuals from these households. The main outcome measures were self-reported mental health problems of psychological distress assessed by the Kessler 10 and depression assessed by Patient Health Questionnaire-9. Unadjusted odd ratios and 95% confidence intervals of factors associated with the two mental health problems were calculated using simple logistic regression with multiple logistic regression using hierarchical modelling to adjust for the potential confounders.

RESULTS

Of the 741 adult participants (55.6% females), 67.4% were aged ≥ 55 years. Based on the questionnaires, 16.2% and 13.6% had threshold-level psychological distress and depression, respectively. Of those with threshold-level K-10 scores, 19.0% and 10.5% had seen a psychologist or a psychiatrist respectively while 24.2% and 9.5% of those experiencing depression had seen a psychologist or a psychiatrist, respectively in the past year. Factors such as being unmarried, current smoker, obesity, were significantly associated with a higher prevalence of mental health problems whereas physical activity, and community participation reduced the risk of mental health problems. Compared to rural towns, the regional town had higher risk of depression which was non-significant after adjusting for community participation and health conditions.

CONCLUSIONS

The high prevalence of psychological distress and depression in this rural population was consistent with other rural studies. Personal and lifestyle factors were more relevant to mental health problems than degree of rurality in Victoria. Targeted lifestyle interventions could assist in reducing mental illness risk and preventing further distress.

The prevalence and correlates of depression among older adults in greater kumasi of the ashanti region

BACKGROUND

Approximately two million Ghanaians suffer from mental disorders including depression. The WHO defines it as an illness characterized by constant sadness and loss of interest in activities that a person usually enjoys doing and this condition is the leading cause of mental disorders; however, the burden of depression on the aged population is fairly unknown. A better appreciation of depression and its predictors is necessary to design appropriate policy interventions. Therefore, this study aims to assess the prevalence and correlates of depression among older people in the Greater Kumasi of the Ashanti region.

METHODS

A cross-sectional study design with a multi-stage sampling approach was employed to recruit and collect data from 418 older adults aged 60 years and above at the household level in four enumeration areas (EAs) within the Asokore Mampong Municipality. Households within each EAs were mapped and listed by trained resident enumerators to create a sampling frame. Data was collected electronically with Open Data Kit application over 30 days through face-to-face interaction using the Geriatric Depression Scale (GDS). The results were summarized using descriptive and inferential statistics. A multivariable logistics regression using a forward and backward stepwise approach was employed to identify the predictors of depression in the study sample. All analyses were performed using STATA software version 16, and the significance level was maintained at a p-value < 0.05 and presented at a 95% confidence interval.

RESULTS

The study achieved a response rate of 97.7% from the estimated sample size of 428 respondents. The mean age was 69.9 (SD = 8.8), and the distribution was similar for both sexes (p = 0.25). The prevalence of depression in this study was 42.1% and dominated by females, older adults (> 80 years), and lower economic class respondents. The rate was 43.4% for both consumers of alcohol and smokers with a history of stroke (41.2%) and taking medication for chronic conditions (44.2%). The predictors of depression in our study were being single, low class [aOR = 1.97; 95% CI = 1.18-3.27] and having other chronic conditions [aOR = 1.86; 95% CI = 1.59-4.62], and the inability to manage ones' own affairs [aOR = 0.56; 95% CI = 0.32-0.97].

CONCLUSION

The study provides data that can inform policy decisions on the care of the elderly with depression in Ghana and other similar countries, confirming the need to provide support efforts towards high-risk groups such as single people, people with chronic health conditions, and lower-income people. Additionally, the evidence provided in this study could serve as baseline data for larger and longitudinal studies.

Culturally Appropriate Assessment of Depression and Anxiety in Older Torres Strait Islanders: Limitations and Recommendations

OBJECTIVES

The aim of the study was to assess the prevalence of anxiety and depression in older Aboriginal and Torres Strait Islander adults.

METHODS

A modified version of the PHQ-9 (KICA-dep) and the Geriatric Anxiety Inventory (GAI) were administered as part of a wider dementia prevalence study conducted in the Torres Strait. Results were compared to diagnoses obtained on Geriatric review to evaluate their applicability in the region.

RESULTS

A total of 236 participants completed the KICA-dep and 184 completed the GAI short form. Of these, 10.6% were identified with depression and 15.8% with anxiety. Some participants found questions about suicide ideation and self-harm offensive and others had difficulty understanding concepts on the GAI. The KICA-dep performed poorly in comparison to diagnosis on geriatric clinical review, so results are unlikely to reflect the true prevalence of depression in the region.

CONCLUSIONS

Further research is required to explore the underlying dimensions of depression and anxiety and terminology used to express mood symptoms in the Torres Strait.

CLINICAL IMPLICATIONS

• Current mental health screening tools are not applicable for the Torres Strait• More work is required to determine how symptoms of depression and anxiety are expressed within Torres Strait communities.

Prevalence of depression in older adults: A systematic review and meta-analysis

Depression is a prevalent mental disorder in older adults, but the prevalence in older adults varies largely across studies due to differences in regional cultures and screening tools. The objective of this review is to systematically evaluate the global prevalence of depression in older adults. PubMed, Embase, Web of Science and Cochran Library databases were searched independently from 2000 to 2021. Subgroups, sensitivity, and meta-regression analyses were performed to address heterogeneity. Publication bias was evaluated using Egger's test. Forty-eight eligible studies were included in this review. The global prevalence of depression in older adults was 28.4%, with high between-study heterogeneity. The meta-analysis showed that the prevalence of depression in older adults is high although it varied with geographic regions, screening tools, sample sizes and representativeness, and study quality. Therefore, it is necessary to carefully consider appropriate screening tools to estimate the prevalence in different regions of a population.

A neural network approach to optimising treatments for depression using data from specialist and community psychiatric services in Australia, New Zealand and Japan

This study investigated the application of a recurrent neural network for optimising pharmacological treatment for depression. A clinical dataset of 458 participants from specialist and community psychiatric services in Australia, New Zealand and Japan were extracted from an existing custom-built, web-based tool called Psynary . This data, which included baseline and self-completed reviews, was used to train and refine a novel algorithm which was a fully connected network feature extractor and long short-term memory algorithm was firstly trained in isolation and then integrated and annealed using slow learning rates due to the low dimensionality of the data. The accuracy of predicting depression remission before processing patient review data was 49.8%. After processing only 2 reviews, the accuracy was 76.5%. When considering a change in medication, the precision of changing medications was 97.4% and the recall was 71.4% . The medications with predicted best results were antipsychotics (88%) and selective serotonin reuptake inhibitors (87.9%). This is the first study that has created an all-in-one algorithm for optimising treatments for all subtypes of depression. Reducing treatment optimisation time for patients suffering with depression may lead to earlier remission and hence reduce the high levels of disability associated with the condition. Furthermore, in a setting where mental health conditions are increasing strain on mental health services, the utilisation of web-based tools for remote monitoring and machine/deep learning algorithms may assist clinicians in both specialist and primary care in extending specialist mental healthcare to a larger patient community.

Prevalence and risk factors for depressive symptoms in patients with neovascular age-related macular degeneration who present for anti-VEGF therapy

PURPOSE

To examine the prevalence and risk factors for depressive symptoms in patients with neovascular age-related macular degeneration (nAMD) presenting for anti-vascular endothelial growth factor (anti-VEGF) therapy.

METHODS

In a clinic-based cohort of 547 patients with nAMD who presented for treatment, the Centre of Epidemiological Studies Depression 10-point scale (CES-D-10) and Mental Health Index (MHI) component of the 36-item Short Form Survey were administered to assess for the presence of depressive symptoms. Logistic regression analyses were used to calculate odds ratios and 95% confidence intervals for factors associated with an increased likelihood of depressive symptoms.

RESULTS

The prevalence of depressive symptoms was 42.04% and 31.78% as per the CES-D-10 and MHI scales, respectively. Poor self-rated health (SRH) is associated with increased odds of depressive symptoms [multivariable-adjusted OR: 3.00 (95% CI 1.90-4.73) for CES-D-10; OR: 2.67 (95% CI 1.67-4.28) for MHI]. Impaired activities of daily living (ADLs) [multivariable-adjusted OR: 2.62 (95% CI 1.56-4.38) for CES-D-10; OR: 3.59 (95% CI 2.10-6.15) for MHI] and a visual function score within the two lowest quartiles were also associated with increased odds of depressive symptoms using both scales.

CONCLUSION

A high prevalence of depressive symptoms was observed among nAMD patients presenting for treatment. Poorer SRH, ADL impairment and reduced visual function were associated with increased odds of depressive symptoms.

Cost-effectiveness evidence of mental health prevention and promotion interventions: A systematic review of economic evaluations

BACKGROUND

The prevention of mental disorders and promotion of mental health and well-being are growing fields. Whether mental health promotion and prevention interventions provide value for money in children, adolescents, adults, and older adults is unclear. The aim of the current study is to update 2 existing reviews of cost-effectiveness studies in this field in order to determine whether such interventions are cost-effective.

METHODS AND FINDINGS

Electronic databases (including MEDLINE, PsycINFO, CINAHL, and EconLit through EBSCO and Embase) were searched for published cost-effectiveness studies of prevention of mental disorders and promotion of mental health and well-being from 2008 to 2020. The quality of studies was assessed using the Quality of Health Economic Studies Instrument (QHES). The protocol was registered with PROSPERO (# CRD42019127778). The primary outcomes were incremental cost-effectiveness ratio (ICER) or return on investment (ROI) ratio across all studies. A total of 65 studies met the inclusion criteria of a full economic evaluation, of which, 23 targeted children and adolescents, 35 targeted adults, while the remaining targeted older adults. A large number of studies focused on prevention of depression and/or anxiety disorders, followed by promotion of mental health and well-being and other mental disorders. Although there was high heterogeneity in terms of the design among included economic evaluations, most studies consistently found that interventions for mental health prevention and promotion were cost-effective or cost saving. The review found that targeted prevention was likely to be cost-effective compared to universal prevention. Screening plus psychological interventions (e.g., cognitive behavioural therapy [CBT]) at school were the most cost-effective interventions for prevention of mental disorders in children and adolescents, while parenting interventions and workplace interventions had good evidence in mental health promotion. There is inconclusive evidence for preventive interventions for mental disorders or mental health promotion in older adults. While studies were of general high quality, there was limited evidence available from low- and middle-income countries. The review was limited to studies where mental health was the primary outcome and may have missed general health promoting strategies that could also prevent mental disorder or promote mental health. Some ROI studies might not be included given that these studies are commonly published in grey literature rather than in the academic literature.

CONCLUSIONS

Our review found a significant growth of economic evaluations in prevention of mental disorders or promotion of mental health and well-being over the last 10 years. Although several interventions for mental health prevention and promotion provide good value for money, the varied quality as well as methodologies used in economic evaluations limit the generalisability of conclusions about cost-effectiveness. However, the finding that the majority of studies especially in children, adolescents, and adults demonstrated good value for money is promising. Research on cost-effectiveness in low-middle income settings is required.

Patient Health Questionnaire 9 (PHQ-9) and General Anxiety Disorder 7 (GAD-7) data contributed by 13,829 respondents to a national survey about COVID-19 restrictions in Australia

While the Patient Health Questionnaire 9 (PHQ-9) and General Anxiety Disorder 7 (GAD-7) are frequently used in mental health research, few studies have reported comprehensive data on these measures from population or community samples. The PHQ-9 and GAD-7 were used as indicators of symptoms of depression and anxiety in a national online anonymous survey to assess the mental health of adults in Australia during the COVID-19 restrictions. The aim of this study was to describe gender- and age-specific PHQ-9 and GAD-7 item and summary data contributed by those who completed this survey. Data were analysed descriptively. Complete survey responses were contributed by 13,829 people. For both measures, item-by-item results, summary statistics (mean, standard deviation, minimum, maximum, median and interquartile range) and prevalence of severity categories are reported for the whole sample, and disaggregated by gender and age groups. These comprehensive data provide a useful point of comparison for future COVID-19-related or other research among population or community samples. Other researchers are encouraged to report detailed PHQ-9 and GAD-7 data in the future, to enable and promote relevant between-group comparisons.

Factors influencing self-management of depression in older adults: a qualitative study

Objectives: A considerable body of work addresses prevalence and treatment options for depression in older adults. However, less is known about their capacity to self-manage their depression. Effective self-management of depression has the potential to improve individuals' quality of life through information, empowerment and perceived control, while enabling more efficient health service utilisation. The aim of this paper was to identify the barriers and facilitators to self-management of depression in older adults.Method: A qualitative study comprising in-depth, semi-structured interviews with 32 older adults with a diagnosis of moderate depression.Results: Three over-arching themes captured the barriers and facilitators to participants' capacity to self-manage their depression. Perspectives on age and depression represented how views of older age and mental health influenced the approach to self-management. Ability to access the health care system concerned the ability to identify and engage with different services and support. Individual capacity for self-management reflected participants' views on and the resources required for effective self-management.Conclusion: This study offers a better understanding of the factors that positively or negatively influence older adults' ability to self-manage their depression. Strategies to improve self-management should address misconceptions about age and depression, and older adults' interest in and capacity to embrace self-management practices.

Socio-demographic characteristics, lifestyle factors, multi-morbid conditions and depressive symptoms among Nepalese older adults

BACKGROUND

Depressive symptoms (DS) are a well-recognized public health problem across the world. There is limited evidence with regard to DS and its associates, such as socio-demographic characteristics, lifestyle factors and chronic conditions in low-income countries like Nepal. In this study, we aimed to assess the level of DS and its relationship with socio-demographic characteristics, lifestyle factors and chronic disease conditions among community dwelling older people in Nepal.

METHODS

We conducted a cross-sectional study of 794 older adults aged 60 or above residing in the rural setting of the Sunsari and Morang districts of eastern Nepal between January and April 2018. Multi-stage cluster sampling was adopted to select the study participants. Data included socio-demographics, lifestyle factors, self-reported chronic disease conditions and the Geriatric depression scale. On Geriatric depression scale, an older adult with a test score greater than five were defined as having depressive symptoms. Determinants of DS were estimated through the generalized estimating equation (GEE) approach by considering exchangeable correlation structure among clusters.

RESULTS

In our study samples, nearly 55.8% of the older adults were found to be suffering from DS. We found a significant association between DS and being female (aOR: 1.25, 95% CI: 0.89-2.09), Buddhism (aOR: 1.95, 95% CI: 1.58-2.42), Dalits (aOR: 2.60, 95% CI: 1.19-5.65), unemployed, low family income (aOR: 1.77, 95% CI: 1.07-2.92), smokers (aOR: 1.49, 95% CI: 1.01-2.20) and having chronic multi-morbid conditions (aOR: 1.67, 95% CI: 1.09-2.55).

CONCLUSIONS

The prevalence of DS was high among community-dwelling older adults in eastern Nepal. Our findings suggest the need for mental health prevention and management programs targeting the older population in rural Nepal.

It’s Not Just Physical: Exercise Physiologist-Led Exercise Program Promotes Functional and Psychosocial Health Outcomes in Aged Care

Regular physical activity has multiple benefits for older adults, including improved physical, cognitive, and psychosocial health. This exploratory study investigated the benefits of a 12-week exercise program for older adults (n = 11 control and n = 13 intervention) living in a residential aged care facility in Perth, Western Australia. The program, prescribed and delivered by an accredited exercise physiologist, aimed to maintain or improve participants’ physical capacity. It comprised one-on-one exercise sessions (1 hr × 2 days/week × 12 weeks), involving a components-approach intervention. Physical performance measures (balance, strength, flexibility, and mobility) were assessed preintervention and postintervention. Qualitative interviews postintervention with residents participating in the exercise intervention, and with family members, staff, and research team members, explored barriers and enablers to participation and perceived psychosocial outcomes. Findings indicate the program provided physical benefits and enhanced social engagement for participants, illustrating the value of providing exercise physiology services in the aged care sector.

Associations between oral health and depressive symptoms: Findings from the Concord Health and Ageing in Men Project

OBJECTIVE

To investigate whether poorer oral health, tooth loss and lower usage of dental services are associated with depressive symptoms in older Australian men.

METHODS

Cross-sectional study of data collected from participants of the Concord Health and Ageing in Men Project. Depressive symptoms were evaluated by the Geriatric Depression Scale. Chewing capacity was estimated by ability to chew 11 food items.

RESULTS

The prevalence of depressive symptoms was 17.5%. Self-evaluated oral health, chewing capacity and the number of natural and decayed teeth were associated with depressive symptoms. After adjusting for multiple confounders, chewing capacity (PR 1.93; 95% CI 1.34-2.79) and decayed teeth (PR 1.68; 95% CI 1.03-2.75) maintained a significant association with depressive symptoms.

CONCLUSION

The direction of causality between oral health and depression is unclear; however, oral health may contribute to depression in older Australian men and depressive symptoms may limit chewing capacity and be aggravated by untreated dental decay.

The Relationship between living alone, sense of belonging, and depressive symptoms among older men: the moderating role of sexual orientation

Objectives: Living alone is a risk factor for depressive symptoms among older men, and is likely to occur due to belongingness needs being unmet. It is proposed the living alone-sense of belonging and living alone-depressive symptoms relations are stronger for gay men than heterosexual men, due to different family circumstances. This research tested a moderated mediation model, specifically whether the relationship between living alone and depressive symptoms is mediated by sense of belonging, and whether the living alone-sense of belonging and living alone-depressive symptoms relationships are moderated by sexual orientation.Method: A community sample of 169 Australian gay men aged 65 to 93 years and 187 Australian heterosexual men aged 65 to 94 years completed the Psychological subscale of the Sense of Belonging Instrument and the Center for Epidemiologic Studies Depression Scale.Results: Results supported the simple mediation model, with living alone being associated directly and indirectly with depressive symptoms via sense of belonging. The conditional indirect effect of living alone on depressive symptoms via sense of belonging was not significant, and therefore the moderated mediation model was not supported.Conclusion: Results imply that older men who live alone are at increased risk of depressive symptoms directly and indirectly via lower levels of sense of belonging.

Behavioural activation in nursing homes to treat depression (BAN-Dep): study protocol for a pragmatic randomised controlled trial

INTRODUCTION

Depression is a common disorder among older people living in residential aged care facilities. Several trials have demonstrated the effectiveness of behavioural therapies in treating depressive symptoms in older adults living in the community and in residential aged care. Behavioural Activation is demonstrably effective even when delivered by non-specialists (staff without formal psychological training), although strategies for adapting its use in residential aged care facilities are yet to be explored. This study will determine whether training residential care staff in the use of a structured Behavioural Activation programme is more effective at decreasing depressive symptoms among older residents than internet-based training about depression recognition and management alone.

METHOD AND ANALYSIS

The behavioural activation in nursing homes to treat depression (BAN-Dep) trial is a pragmatic two-arm parallel clustered randomised controlled trial. It will recruit 666 residents aged 60 or older from 100 residential aged care facilities, which will be randomly assigned to the Behavioural Activation or control intervention. Staff in both treatment groups will be encouraged to complete the Beyondblue Professional Education to Aged Care e-learning programme to improve their recognition of and ability to respond to depression in older adults. Selected staff from intervention facilities will undergo additional training to deliver an 8-module Behavioural Activation programme to residents with subthreshold symptoms of depression-they will receive ongoing Mental support from trained Behavioural Activation therapists. Outcome measures will be collected by blind research officer at baseline and after 3, 6 and 12 months. The Patient Health Questionnaire-9 is the primary outcome measure of the study.

ETHICS AND DISSEMINATION

The trial will comply with the principles of the Declaration of Helsinki for Human Rights and is overseen by the University of Western Australia (reference RA/4/20/4234) and Melbourne Health (reference number HREC/18/MH/47) Ethics Committees. The results of this research project will be disseminated through publications and/or presentations in a variety of media to health professionals, academics, clinicians and the public. Only de-identified group data will be presented.

Exercise, Mood, Self-Efficacy, and Social Support as Predictors of Depressive Symptoms in Older Adults: Direct and Interaction Effects

Background

Depression is a chronic condition that affects up to 15% of older adults. The healthogenic effects of regular exercise are well established, but it is still unclear which exercise-related variables characterise the antidepressant effects of exercise. Thus, the purpose of this study was to examine the extent to which exercise-related variables (exercise behaviour, exercise-induced mood, exercise self-efficacy, and social support) can predict depressive symptoms in a cohort of community-dwelling older adults.

Methods

This study employed a cross-sectional analysis of questionnaire data from a sample of 586 community-dwelling older Australians aged 65 to 96 years old. Participants completed the Center for Epidemiologic Studies Depression Scale, modified CHAMPS Physical Activity Questionnaire for Older Adults, Four-Dimension Mood Scale, Self-Efficacy for Exercise Scale, and Social Provisions Scale – Short Form. Bivariate correlations were performed, and hierarchical multiple regression was subsequently used to test the regression model.

Results

Exercise behaviour, exercise-induced mood, exercise self-efficacy, and social support were all negatively associated with depressive symptoms (r = −0.20 to −0.56). When the variables were entered as predictors into the hierarchical multiple regression model, social support was the strongest predictor of depressive symptoms (β = −0.42), followed by exercise-induced mood (β = −0.23), and exercise self-efficacy (β = −0.07). Exercise behaviour did not explain any additional variance in depressive symptoms. A modest interaction effect was also observed between exercise-induced mood and social support.

Conclusion

These findings indicate that social support is the strongest predictor of depressive symptomology in community-dwelling older adults, particularly when combined with positive exercise-induced mood states. When addressing the needs of older adults at risk of depression, healthcare professionals should consider the implementation of exercise programmes that are likely to benefit older adults by improving mood, enhancing self-efficacy, and building social support.

Prevalence of depressive symptoms and its associated factors among healthy community-dwelling older adults living in Australia and the United States

OBJECTIVE

This study was conducted to estimate prevalence rates and factors associated with depressive symptoms indexed by the Centre for Epidemiological Studies-Depression (CES-D-10) score in a large sample of community-dwelling healthy older adults from Australia and the United States. Convergent and divergent validity of the CES-D-10 were also examined.

METHODS

A total of 19 114 individuals aged greater than or equal to 65 years old were enrolled from a primary prevention clinical trial. Depressive symptoms were classified using the CES-D-10 score greater than or equal to 8 and greater than or equal to 10. Gender-specific prevalence for subgroups according to sociodemographic characteristics were reported, and factors associated with depressive symptoms were estimated.

RESULTS

The overall prevalence rates of depressive symptoms were 9.8%, 95% CI, 8.5-11.2 and 5.0%, 95% CI, 4.0-6.0, according to the CES-D-10 score greater than or equal to 8 and greater than or equal to 10, respectively. Depressive symptoms were more common in women, individuals with less than 12 years of education, those living alone or in a residential care, ethnic minorities, current smokers, and former alcohol users. Convergent and divergent validities of the CES-D-10 were confirmed by observing strong negative association with the SF-12 mental health component and a modest negative association with SF-12 physical component, respectively.

CONCLUSIONS

This study reports the prevalence of depressive symptoms in Australian and US community-dwelling healthy older populations. These findings emphasize the high burden of the condition and factors associated with depressive symptoms, to better inform clinicians and help with early detection and treatment of depression in this age group.

Resiliency among older adults: dispositional hope as a protective factor in the insomnia-depressive symptoms relation

OBJECTIVES

Depression is a significant mental health issue among older Australian adults. Research has indicated that insomnia is a key risk factor for the development of depressive symptoms in older adults, and that dispositional hope may be protective against the development of depressive symptoms in this population. This study examined whether dispositional hope and its dimensions, agency and pathways, moderated the relationship between insomnia symptoms and depressive symptoms among older Australian adults.

METHOD

A community sample of 88 men (M_age = 71.11, SD_age = 5.54) and 111 women (M_age = 70.25, SD_age = 4.64), aged 65-94 years, completed the Insomnia Severity Index, Adult Dispositional Hope Scale, and Centre of Epidemiologic Studies Depression Scale.

RESULTS

After controlling for gender, age, relationship status, education level, method of participation, and perceived physical health, results supported the moderation models. The insomnia-depressive symptoms relation was significant for older adults with low and average (but not high) levels of dispositional hope, agency, and pathways. The Johnson-Neyman analyses indicated that the insomnia-depressive symptoms relation was significant for older adults who scored below 27.10 on dispositional hope, below 13.73 on agency, and below 13.49 and above 15.64 on pathways.

CONCLUSION

The results of this study imply that interventions aimed at increasing dispositional hope, agency, and pathways among older adults who experience symptoms of insomnia may reduce their depressive symptoms. A cautionary note, however, is that very high scores on pathways among older adults who experience insomnia symptoms may be detrimental to their mental health.

Common mental disorders among Indigenous people living in regional, remote and metropolitan Australia: a cross-sectional study

OBJECTIVE

To determine, using face-to-face diagnostic interviews, the prevalence of common mental disorders (CMD) in a cohort of adult Indigenous Australians, the cultural acceptability of the interviews, the rates of comorbid CMD and concordance with psychiatrists' diagnoses.

DESIGN

Cross-sectional study July 2014-November 2016. Psychologists conducted Structured Clinical Interviews for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision Axis I Disorders (SCID-I) (n=544). Psychiatrists interviewed a subsample (n=78).

SETTING

Four Aboriginal Medical Services and the general community located in urban, regional and remote areas of Southern Queensland and two Aboriginal Reserves located in New South Wales.

PARTICIPANTS

Indigenous Australian adults.

OUTCOME MEASURES

Cultural acceptability of SCID-I interviews, standardised rates of CMD, comorbid CMD and concordance with psychiatrist diagnoses.

RESULTS

Participants reported that the SCID-I interviews were generally culturally acceptable. Standardised rates (95% CI) of current mood, anxiety, substance use and any mental disorder were 16.2% (12.2% to 20.2%), 29.2% (24.2% to 34.1%), 12.4% (8.8% to 16.1%) and 42.2% (38.8% to 47.7%), respectively-6.7-fold, 3.8-fold, 6.9-fold and 4.2-fold higher, respectively, than those of the Australian population. Differences between this Indigenous cohort and the Australian population were less marked for 12-month (2.4-fold) and lifetime prevalence (1.3-fold). Comorbid mental disorder was threefold to fourfold higher. In subgroups living on traditional lands in Indigenous reserves and in remote areas, the rate was half that of those living in mainstream communities. Moderate-to-good concordance with psychiatrist diagnoses was found.

CONCLUSIONS

The prevalence of current CMD in this Indigenous population is substantially higher than previous estimates. The lower relative rates of non-current disorders are consistent with underdiagnosis of previous events. The lower rates among Reserve and remote area residents point to the importance of Indigenous peoples' connection to their traditional lands and culture, and a potentially important protective factor. A larger study with random sampling is required to determine the population prevalence of CMD in Indigenous Australians.

Vasomotor symptoms are associated with depressive symptoms in community-dwelling older women

OBJECTIVE

To assess the prevalence of, and factors associated with, moderate-to-severe depressive symptoms in community-dwelling older Australian women.

METHODS

A questionnaire-based, cross-sectional study was conducted amongst community-dwelling older women. Participants were recruited between April and August 2014 from a national database based on the electoral roll. Depressive symptoms were assessed by the Beck Depression Inventory-II (BDI-II) tool. Vasomotor symptoms (VMS), vulvovaginal atrophy (VVA), and pelvic floor symptoms were assessed using validated questionnaires. Women were provided a comprehensive list of psychotropic medications (antidepressants, benzodiazepines, antipsychotics, and mood stabilizers) to identify their use over the preceding month.

RESULTS

In all, 1,534 women completed the BDI-II. Overall, 34.2% (95% confidence interval [CI] 31.8%-36.7%) of women had VMS, 6.3% (95% CI 5.2%-7.7%) had moderate-to-severe depressive symptoms (BDI-II score ≥20), 26.8% (95% CI 24.6%-29.1%) had used any psychotropic medication in the previous month, and 17.5% (95%CI: 15.6-19.5%) had taken an antidepressant.Moderate-to-severe depressive symptoms were more common among women using antidepressants compared with nonusers (16.6% vs 4.3%; P < 0.001). Obesity (adjusted odds ratio [AOR] 2.18, 95% CI 1.17-4.04), living in financially insecure housing (AOR 3.84, 95% CI 2.08-8.08), being a caregiver to another person (AOR 2.39, 95% CI 1.36-4.19), being a smoker (AOR 2.28, 95% CI 1.12-4.66), having VMS (AOR 1.67, 95% CI 1.03-2.62), having pelvic floor dysfunction (AOR 1.78, 95% CI 1.08-2.94), and having vaginal dryness during intercourse (AOR 1.84, 95% CI 1.06-3.22, P < 0.05) were positively and independently associated with moderate-to-severe depressive symptoms. Being currently partnered (AOR 0.57, 95% CI 0.33-0.97) and employed (AOR 0.38, 95% CI 0.16-0.92) were associated with a lower likelihood of depressive symptoms.

CONCLUSIONS

In older women, depressive symptoms are common and are associated with social and financial insecurity, and with VMS.

Relationship between Physical Disability and Depression by Gender: A Panel Regression Model

Background

Depression in persons with physical disabilities may be more common than in the general population. The purpose of this study was to examine the relationship between physical disability and depression by gender among adults, using a large, nationally representative sample.

Methods

This study used data from the Korean Longitudinal Study of Aging, Wave one through four, and ran a series of random effect panel regression models to test the relationship between physical disability status and depression by gender. We tested the moderating effect of gender on the relationship between disability status and depression level by examining the significance of the cross-product term between disability status and gender.

Results

After controlling for self-rated health, marital status, employment status, education, and age, subjects who were female or diagnosed as having any disability presented higher levels of depression scores. Further, the difference in terms of their depression level measured by Center for Epidemiologic Studies Short Depression Scale (CES-D 10) scores between those who were diagnosed as having any disability and those who were not was greater for females than for their male counterparts.

Conclusion

This study reaffirmed that disability is the risk factor of depression, using longitudinal data. In addition, female gender is the effect modifier rather than the risk factor. The effect of gender in the non-disability group, mostly composed of older persons, is limited. On the contrary, the female disability group showed more depressive symptoms than the male disability group. The gender difference in the disability group and the role of culture on these differences need further research.

The relationship between living alone and depressive symptoms among older gay men: the moderating role of sense of belonging with gay friends

BACKGROUND

Living alone is a risk factor for depressive symptoms among older adults, although it is unclear if it is a risk factor for older gay men. A sense of belonging to the gay community is protective and might compensate for living alone. This research investigated whether a sense of belonging with gay friends weakened the relationship between living alone and depressive symptoms among older gay men.

METHODS

A community sample of 160 Australian gay men aged 65-92 years completed the Center for Epidemiologic Studies Depression Scale and two visual analogue scales assessing a sense of belonging with gay friends.

RESULTS

Results supported the moderation model, with increasing levels of belonging with gay friends weakening the relationship between living alone and depressive symptoms.

CONCLUSION

Results imply that enhancing a sense of belonging with gay friends among older gay men who live alone is likely to be a protective factor in relation to depressive symptoms.

Late life changes in mental health: a longitudinal study of 9683 women

OBJECTIVES

To identify latent subgroups of women in late life who are alike in terms of their mental health trajectories.

METHOD

Longitudinal data are for 9683 participants in the 1921-1926 cohort of the Australian Longitudinal Study on Women's Health, who completed at least two surveys between 1999 (aged 73-78 years) and 2008 (aged 82-87 years). Mental health was measured using the five-item mental health inventory (MHI-5). Latent profile analysis uncovered patterns of change in MHI-5 scores.

RESULTS

Three patterns of change were identified for women who were still alive in 2008 (n = 7061), and three similar patterns for deceased women (n = 2622): (1) 'poor mental health' representing women with low MHI-5 scores, (2) 'good mental health' and (3) 'excellent' mental health, where scores remained very high. Deceased women had lower mental health scores for each class. Remote areas of residence, higher education, single marital status, higher Body Mass Index (BMI) and falls were the covariates associated with mental health in the survivor group. For the deceased group, education, BMI and falls were significant. Arthritis, stroke, heart disease, bronchitis/emphysema, diabetes and osteoporosis were associated with worse mental health for both groups, while asthma increased these odds significantly for the survivor group only. Hypertension and cancer were not significant predictors of poor mental health.

CONCLUSION

The results show associations between chronic disease and level of mental health in older age, but no evidence of a large decline in mental health in the period prior to death.

Prevalence of depression and its associated factors among Chinese elderly people: A comparison study between community-based population and hospitalized population

Depression is common among elderly people, but people from various study settings were at different levels of risk for depression. However, most of the existing studies were conducted among community population, and little was known about depression among institutionalized population. In this study, using a national sample, we aimed to compare the prevalence rate of depression and its associated factors between community-dwelling elderly people (CDEP) and elderly medical inpatients (EMI). Data for this study was derived from a national survey of the 2011 Comprehensive Assessment of Elderly Health. The Geriatric Depression Scale was used to assess depression. The results indicated that the prevalence rate of depression among EMI was significantly higher than that in CDEP (18.1% vs 11.6%, P<0.001). Physical health status was found to be the most important factor associated with depression among both groups. This study revealed a high prevalence rate of depression among Chinese elderly people, especially for those medically institutionalized. It's essential to pay more efforts on the training of general practitioners for early screening and identification of depression on the admission of elderly patients and during their hospitalization, and case management of the elderly medical inpatients on assessment and treatment for depression may be beneficial.

Internet-delivered treatment for older adults with anxiety and depression: implementation of the Wellbeing Plus Course in routine clinical care and comparison with research trial outcomes

BACKGROUND

The Wellbeing Plus Course is an internet-delivered psychological intervention for older adults with anxiety or depression.

AIMS

To compare the effectiveness of the Wellbeing Plus Course in a public health setting (clinic group) with its efficacy in a randomised controlled trial (research group).

METHOD

Participants (n=949) were Australian adults aged 60 and above. Primary outcome measures were the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7).

RESULTS

Initial symptom severity was higher in the clinic group and course completion was lower. Both groups showed significant symptom reductions at post-treatment and were satisfied with the treatment. Results were maintained at 3-month follow-up. Within-group symptom changes were comparable between settings; there were no between-group differences on primary outcomes or satisfaction.

CONCLUSIONS

The Wellbeing Plus Course is as effective and acceptable in routine clinical care, as it is in controlled research trials.

Age Matters: Exploring Correlates of Self-Rated Health Across Four Generations of Australian Males

The importance of addressing health disparities experienced by boys and men reached tangible prominence in Australia with adoption of the 2010 National Male Health Policy and the establishment of a national longitudinal study on male health-Ten to Men. Ten to Men is based on a holistic model of health with a strong focus on social determinants and health and well-being over the life course. Given the life course focus, we set out to assess if health-related characteristics and the correlates of self-rated health differ across the life course among four sociologically defined generations of Australian males. While some differences in the correlates of good or excellent health were observed across generations, addressing obesity and depression appear to be important for improving the health of Australian males of all ages.

Prospective longitudinal study of testosterone and incident depression in older men: The Health In Men Study

BACKGROUND

Depression in older men has been associated with low circulating testosterone concentration but data from prospective studies are limited.

METHODS

We conducted a prospective longitudinal study in a community representative cohort of 3179 older men free of clinically significant depressive symptoms at baseline. The main objective of this study was to determine if low serum testosterone, dihydrotestosterone and estradiol concentrations are associated with the development of depressive symptoms. Incident depression was assessed with the Patient Health Questionnaire and via an electronic health record database (The West Australian Data Linkage System). The main exposures of interest were serum testosterone, dihydrotestosterone and estradiol measured by liquid chromatography-mass spectrometry and calculated free testosterone in baseline blood samples (collected between 2001 and 2004).

RESULTS

One hundred and thirty five men (4.2%) developed depression over a median follow up time of 9.4 years (range 8.4-10.9). Men with incident depression were older (median age 77.7 vs 76.1 years, z=-3.82, p=0<0.001) and were more likely to have cardiovascular disease (43.0% vs 32.6%, χ(2)=6.32, p=0.012) and diabetes (22.2% vs 13.2%, χ(2)=8.95, p=0.003). Low serum total testosterone (<6.4 nmol/L) was associated with incident depression (HR 2.07, 95%CI 1.17-3.68) and this remained significant after adjustment for relevant potential confounding factors (HR 1.86, 95%CI 1.05-3.31). Low serum dihydrotestosterone, estradiol and calculated free testosterone were not associated with risk of depression.

CONCLUSIONS

Low serum total testosterone, but not calculated free testosterone, was associated with incident depression in this sample of older men.

Treating anxiety and depression in older adults: randomised controlled trial comparing guided v. self-guided internet-delivered cognitive-behavioural therapy

BACKGROUND

Symptoms of anxiety and depression are prevalent in older adults.

AIMS

To compare clinician-guided and self-guided versions of a transdiagnostic internet-delivered cognitive-behavioural therapy (iCBT) intervention for adults aged 60 years and above.

METHOD

Adults (n=433) with symptoms of anxiety and depression were randomly allocated to: (1) clinician-guided treatment (n=153); (2) initial clinician interview followed by self-guided treatment (n=140); or (3) self-guided treatment without interview (n=140).

RESULTS

Large reductions (d ≥1.00) in symptoms of depression and anxiety were observed across groups, and sustained at follow-up. No differences were observed in clinical outcomes or satisfaction ratings. Age did not affect outcomes.

CONCLUSIONS

Carefully developed iCBT interventions may significantly reduce symptoms of anxiety and depression in older adults when delivered in either clinician-guided or self-guided formats.

Clinical and cost-effectiveness of therapist-guided internet-delivered cognitive behavior therapy for older adults with symptoms of depression: a randomized controlled trial

Depression is a common and significant health problem among older adults. Unfortunately, while effective psychological treatments exist, few older adults access treatment. The aim of the present randomized controlled trial (RCT) was to examine the efficacy, long-term outcomes, and cost-effectiveness of a therapist-guided internet-delivered cognitive behavior therapy (iCBT) intervention for Australian adults over 60 years of age with symptoms of depression. Participants were randomly allocated to either a treatment group (n=29) or a delayed-treatment waitlist control group (n=25). Twenty-seven treatment group participants started the iCBT treatment and 70% completed the treatment within the 8-week course, with 85% of participants providing data at posttreatment. Treatment comprised an online 5-lesson iCBT course with brief weekly contact with a clinical psychologist, delivered over 8 weeks. The primary outcome measure was the Patient Health Questionnaire-9 Item (PHQ-9), a measure of symptoms and severity of depression. Significantly lower scores on the PHQ-9 (Cohen's d=2.08; 95% CI: 1.38 - 2.72) and on a measure of anxiety (Generalized Anxiety Disorder-7 Item) (Cohen's d=1.22; 95% CI: 0.61 - 1.79) were observed in the treatment group compared to the control group at posttreatment. The treatment group maintained these lower scores at the 3-month and 12-month follow-up time points and the iCBT treatment was rated as acceptable by participants. The treatment group had slightly higher Quality-Adjusted Life-Years (QALYs) than the control group at posttreatment (estimate: 0.012; 95% CI: 0.004 to 0.020) and, while being a higher cost (estimate $52.9l 95% CI: -23.8 to 128.2), the intervention was cost-effective according to commonly used willingness-to-pay thresholds in Australia. The results support the potential efficacy and cost-effectiveness of therapist-guided iCBT as a treatment for older adults with symptoms of depression.

Mortality among people with severe mental disorders who reach old age: a longitudinal study of a community-representative sample of 37,892 men

Background

Severe mental illnesses are leading causes of disability worldwide. Their prevalence declines with age, possibly due to premature death. It is unclear, however, if people with severe mental disorders who reach older age still have lower life expectancy compared with their peers and if their causes of death differ.

Methods and Findings

Cohort study of a community-representative sample of 37892 Australian men aged 65–85 years in 1996–1998. Follow up was censored on the 31st December 2010. Lifetime prevalence of schizophrenia spectrum, bipolar, depressive and alcohol-induced disorder was established through record linkage. A subsample of 12136 consented to a face-to-face assessment of sociodemographic, lifestyle and clinical variables. Information about causes of death was retrieved from the Australian Death Registry. The prevalence of schizophrenia spectrum, bipolar, depressive and alcohol-induced disorders was 1.2%, 0.3%, 2.5% and 1.8%. The mortality hazard for men with a severe mental disorder was 2.3 and their life expectancy was reduced by 3 years. Mortality rates increased with age, but the gap between men with and without severe mental disorders was not attenuated by age. Cardiovascular diseases and cancer were the most frequent causes of death. The excess mortality associated with severe mental disorders could not be explained by measured sociodemographic, lifestyle or clinical variables.

Conclusions

The excess mortality associated with severe mental disorders persists in later life, and the causes of death of younger and older people with severe mental disorders are similar. Hazardous lifestyle choices, suboptimal access to health care, poor compliance with treatments, and greater severity of medical comorbidities may all contribute to this increased mortality. Unlike young adults, most older people will visit their primary care physician at least once a year, offering health professionals an opportunity to intervene in order to minimise the harms associated with severe mental disorders.

The Kimberley assessment of depression of older Indigenous Australians: prevalence of depressive disorders, risk factors and validation of the KICA-dep scale

OBJECTIVE

This study aimed to develop a culturally acceptable and valid scale to assess depressive symptoms in older Indigenous Australians, to determine the prevalence of depressive disorders in the older Kimberley community, and to investigate the sociodemographic, lifestyle and clinical factors associated with depression in this population.

METHODS

Cross-sectional survey of adults aged 45 years or over from six remote Indigenous communities in the Kimberley and 30% of those living in Derby, Western Australia. The 11 linguistic and culturally sensitive items of the Kimberley Indigenous Cognitive Assessment of Depression (KICA-dep) scale were derived from the signs and symptoms required to establish the diagnosis of a depressive episode according to the DSM-IV-TR and ICD-10 criteria, and their frequency was rated on a 4-point scale ranging from 'never' to 'all the time' (range of scores: 0 to 33). The diagnosis of depressive disorder was established after a face-to-face assessment with a consultant psychiatrist. Other measures included sociodemographic and lifestyle factors, and clinical history.

RESULTS

The study included 250 participants aged 46 to 89 years (mean±SD = 60.9±10.7), of whom 143 (57.2%) were women. The internal reliability of the KICA-dep was 0.88 and the cut-point 7/8 (non-case/case) was associated with 78% sensitivity and 82% specificity for the diagnosis of a depressive disorder. The point-prevalence of a depressive disorder in this population was 7.7%; 4.0% for men and 10.4% for women. Heart problems were associated with increased odds of depression (odds ratio = 3.3, 95% confidence interval = 1.2,8.8).

CONCLUSIONS

The KICA-dep has robust psychometric properties and can be used with confidence as a screening tool for depression among older Indigenous Australians. Depressive disorders are common in this population, possibly because of increased stressors and health morbidities.

Mental health service utilization among Korean elders in Korean churches: preliminary findings from the Memory and Aging Study of Koreans in Maryland (MASK-MD)

BACKGROUND

Korean Americans (KA) comprise the fourth largest Asian-American subgroup, with a population estimated at nearly 1.7 million, and the vast majority (up to 85%) of KA elders attends ethnic churches. Despite the rapid increase of the KA elderly population, data on mental health service utilization among KA elders are scarce.

METHOD

Based on a cluster sampling method, the Memory and Aging Study among Koreans in Maryland (MASK-MD) recruited and assessed 630 KA elders (mean age: 70.9 ± 6.1 years; 68.9% female) in KA churches for depression, dementia, and level of mental health service utilization. The Korean versions of the Patient Health Questionnaire (PHQ-9K) and Mini-mental Status Examination (MMSE-KC) were administered by trained community health workers.

RESULTS

Of the 630 participants, 23.2% and 7.3% had PHQ-9 scores of 5 ('mild depression') or above and 10 or above ('clinical depression'), respectively. In addition, 7.0% scored below the age- and education-specific cutoff values for probable dementia based on the MMSE-KC. Of the 92 participants with 'clinical depression' or having thoughts of death or self-injury, only 16 (17%) reported utilizing mental health services. Likewise, of 56 participants with probable dementia, only 3 (7.3%) sought treatment from a health care provider.

CONCLUSION

The prevalence of depression and cognitive impairment are high in community-dwelling KA elders attending KA churches, but the rate of mental health service utilization among depressed or cognitively impaired Korean elders is low. Further research is warranted to identify barriers to and strategies for adequate mental health care for Korean immigrant elders.

Vision, quality of life and depressive symptoms after first eye cataract surgery

BACKGROUND

Cataract affects not only vision, but also performance of everyday tasks, participation in social activities, quality of life and possibly depression. Depression is a major health issue for older adults. It is estimated that 6%-20% of community-dwelling older Australians experience depression. The aim of this study was to investigate changes in vision-related quality of life and depressive symptoms after first eye cataract surgery and to determine which visual measures affect the change in these outcomes.

METHODS

In 2009 and 2010, 99 participants with bilateral cataract were recruited. Visual measures including visual acuity, contrast sensitivity and stereopsis were assessed 1 week before and 12 weeks after first eye cataract surgery. Vision-related quality of life was measured using the 25-item National Eye Institute Visual Function Questionnaire. Depressive symptoms were assessed by the 20-item Center for Epidemiological Studies Depression Scale. Separate regression analyses were undertaken to determine the association between visual measures and changes in vision-related quality of life and depressive symptoms after first eye cataract surgery.

RESULTS

Overall, vision-related quality of life improved after first eye cataract surgery. There was a small, non-clinically significant improvement in depressive symptoms after surgery. Improvement in vision-related quality of life after first eye cataract surgery was associated with improved contrast sensitivity in the operated eye (P < 0.001), whereas improvement in depressive symptoms after surgery was associated with improved stereopsis (P = 0.032).

CONCLUSIONS

Contrast sensitivity and stereopsis, but not visual acuity, were significant factors affecting improvement in vision-related quality of life or depressive symptoms after first eye cataract surgery.

Age related differences in mental health scale scores and depression diagnosis: adult responses to the CIDI-SF and MHI-5

Inconsistencies surrounding the prevalence levels of depression in later life suggest that the measurement of depression in older people may be problematic. The current study aimed to map responses to a depressive symptom scale, the Mental Health Index-5 (MHI-5) which is part of the Short form 36 (SF-36, Ware et al., 1993) against the diagnostic screening items of the Composite International Diagnostic Instrument-Short Form (CIDI-SF, Kessler et al., 1998) to examine disagreement rates across age groups. The study examined data from a national random sample of 10,641 participants living in Ireland, 58.8% were female and 19% were over 65 (SLÁN, 2007). CIDI-SF depression screening endorsement was lower in older groups, whereas mean MHI-5 depressive symptoms showed less change across age groups. Results showed that the odds of MHI-5 endorsers aged 18-44 endorsing CIDI-SF screening questions were 5 times and 4.5 times (dysphoria and anhedonia, respectively) greater than the odds of people aged 75 or more endorsing these items. Findings suggest that although the risk of depressive disorder may decrease with age, complex diagnostic screening questions may exaggerate lower rates of depression among older people.

Prevalence and correlates of depression among Australian women: a systematic literature review, January 1999- January 2010

Background

Little is known about the prevalence and correlates of depression among Australian women. This systematic review of depression among women in Australia, the largest identified to date, highlights the prevalence and correlates of depression across the life span.

Results

The report adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: The PRISMA Statement (PRISMA). Six health related databases were selected: Medline, PsychInfo, SCOPUS, Cinhal, Informit and Cochrane Systematic Reviews. 1,888 initial articles were found, and 111 articles were considered relevant for review. Prevalence rates of depression among women ranged from 2.6% to 43.9%. Higher rates were reported for younger women, or specific population groups. Most significant correlates included, age, adverse life events, tobacco use, sole motherhood, and previous mental health problems.

Conclusions

Limitations include the scope of the investigation’s aims and inclusion criteria, and the failure to identify gender specific data in most studies. Publication bias was likely, given that only papers reported (or translated) in English were included. Despite the breadth of information available, there were noticeable gaps in the literature. Some studies reported on affective disorders, but did not specifically report on depression; it is concluded that each mental illness warrants separate investigation. It was also common for studies to report a total prevalence rate without separating gender. This report recommends that it is vital to separate male and female data. The report concludes that more research is needed among mid-age women, Indigenous women, non-heterosexual women and Culturally and Linguistically Diverse (CALD) women.
